SPECIFICATION forming part of Letters Patent No. 578,786, dated March16, 1897.

Application led April 10, 1896.

To all whom t may concern:

Be it known that I, GEORGE S. TIFFANY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Car-Seal Locks, (CaseNo. 2,) of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming apart of this specilication.

My invention relates to car-seal locks, its object being to provide apin for car locks or fasteners in which the seal may be readily lockedand in a manner to prevent the withdrawal of the pin without firstbreaking and removing the seal. In ear-fasteners as usually employed ahasp is pivoted to the door and adapted to be placed over a stapleprovided upon the door-frame, a pin being provided which is passedthrough the staple to prevent the removal of the hasp. The withdrawal ofthe pin is prevented by a seal, in the form of a strip of tin or sheetmetal, which is passed through an eye or slot in the end of the pin, theends of the strip being secured together by a soft-metal rivet, whichpasses through holes provided in the ends of the strip, the ends orheads of the rivet being pressed against the faces of the sheetnnetalstrip, a special tool being employed for pressing the rivet into form.

It is the object of the present invention to provide a form of lockwhereby a seal requiring a special tool in its application to thefastener may be dispensed with, and, furthermore, to employ as many ofthe parts of the fasteners at present upon the cars as possible.

In accordance with the present invention all of the parts of the presentfasteners except the pins may be employed, the ordinary pin beingreplaced by a pin having a separable head or plunger, between which andthe body of the pin the seal is locked in such a manner that the removalof the pin from the staple is prevented by the presence of the seal, theremoval of the seal from the pin being prevented without first breakingthe same. The seal is preferably in the form of a small piece of sheetmetal, which is inserted into a slot in Serial No. 536,904. (No model.)

.withdrawal of the plunger. By this construction the seal is locked inposition bya simple movement of the parts of the pin and without theemployment of any tool, and the seal is locked in position in a mannerto effeetually prevent the removal of the pin Without first breaking andremoving the seal. 'Furthermore, the lock of the present invention maybe readily and at small cost applied to the existing fasteners by thesubstitution of the pin of the present invention for the usual solidpins.

I am aware that it has heretofore been proposed to secure the seal tothe fastener through the agency of a detachable pin or plunger, but insuch constructions a casting carrying the socket is mounted upon thecar, within which socket the pin passes, whereas, in accordance with thepresent invention, the seallock is wholly within the pin, whichcomprises a shell or body within which fits a plunger or head, betweenwhich and the body the seal is locked. A

The lock of the present invention may be utilized by substituting thepin herein for the ordinary pins in use, while the employment of thelock above referred to necessitates the discarding of al1 of the partsof the fasteners now in use and the complete requipment of the cars.

I have illustrated my invention in the accompanying drawings, in Which-Figure l is a view of a hasp-and-staple lock provided with the pin of myinvention. Fig. 2 is a sectional view of the pin, showing the plunger inits innermost or locked position. Fig. 3 is a similar sectional viewshowing the plunger withdrawn. Fig. 4 is a sectional view on a plane atright angles to that of Fig. 2.

Fig. 5 is a sectional view of the pin o n line 5 5, Fig. 3. Fig. 6 is aview ofthe end portion of the body of the pin. Fig. 7 is a view of thestaple I employ in one form of myinvention. Fig. 8 is a view of' amodified form of seal.-

Like letters refer to like parts in the several figures.

The hasp a is secured at one end to a staple b and is provided at theopposite end with a slot, through which passes the staple c. The pin dpasses through the staple c, thus locking the hasp in position. The bodyd of the pin is in the form of a shell or hollow tube carrying upon theinterior a shelf or lug da, which preferably extends around the interiorof the tube and is provided with a slot d5 on one side. The plunger emoves within the bore of the shell and carries upon the end a pivoteddog e', which when the plunger is thrust in engages the lug d2 and locksthe plunger within the shell. presses against the end of the dog e toyieldingly press the same into engagement with the lug. The dog e ispivoted within a slot e4, provided in the end of the plunger, ajournal-pin passing through the end of the plunger and the dog.

A peripheral channel e5 is provided around the plunger, and a pin cl3projects into saidv channel to limit the movement of the plunger. Nearthe outer end of the plunger is provided a transverse channel e, whichwhen the plunger is withdrawn lies wholly beyond the end of the shell,through which channel the sheet-metal seal 7l may be passed to the slote7. When the plunger is thrust in, the seal resting within the slot e7passes into the slot @Z4 in the end of the shell d, and, the dogengaging the lug, the plunger is thus locked within the slots e7 and d4of the plunger and the shell, respectively, and the rotation of theplunger is prevented without the previous breaking and removal of theseal.

Vhen it is desired to remove the pin, the seal may be broken along theweakened line 7L and the seal withdrawn from the pin, after which thepin may be withdrawn from the staple. When it is desired to insert a newseal, the plunger may be given a partial rotation to permit the passageof the dog e through the slot d5 and thus disengage the spring-catch,after which the plunger may be withdrawn for the insertion of a newseal.

As a further precaution against tampering with thelook I preferablyprovide a longitudinal ridge or web d6 upon one side of the pin, andprovide in the staple a recess c', Fig. 7, `in which the ridge d6 isadapted to fit, the recess being so loc-ated that the ridge upon the pinwill lie upon the back of the pin when in position, that is, upon theside toward the side of the car. The longitudinal slot d4 is preferablysituated to one side of the center, as is likewise the slot e7 in theplunger, so that when the seal is in place the plunger will it into theshell in one position only and will 1 1' 2 A short spiing e not iit ifthe plunger be rotated through a halfrevolution. The slots are sosituated that the dog engages the lug at a point in the plane of theridge. The dog thus rests against the rear wall of the shell andtampering therewith is prevented.

The seal is preferably made in the form illustrated, in which the endspossess greater Width than the middle portion, to thereby prevent theendwise withdrawal of the seal through the slot. While I preferablyemploy this form of seal, other shapes may be employed. In order toprevent the bending of the seal about the pin to permit the withdrawalof the pin and seal through the eye of the staple, one or morecorrugations h2, preferably longitudinal, are provided. In practice thepins are fitted to the staples, so that the pin closely engages thewalls of the eye of the staple.

Having described my invention, what I claim as new, and desire tosecu-re by Letters Patent, is-

1. In a ear-seal look, the combination with a hasp and a staple, of apin containing the seal-lock and comprising a shell provided with ashoulder or lateral extension at one end and open at the opposite end, aplunger extending into the open end of said shell, a

-oateh for locking said plunger in said shell when thrust in except whenthe plunger is rotated, transverse slots provided at the open end ofsaid shell and a transverse slot in the plunger registering with theslots in said shell when the plunger is thrust in, a dat seal titting insaid slots and provided with extensions on opposite sides of the shellto prevent the Withdrawal of the seal, the shank of said pin passingthrough the eye of the staple and resting with the shoulder-on one sideof the staple and the looked seal on the other side, substantially asdescribed, and for purpose set forth.

2. In a earseal lock, the combination with a staple and a hasp, of a pinfor insertion through said staple and provided with transverse slotswithin which a iiat or sheet-like seal is clamped, the ends of the sealthus extending beyond t'he pin to prevent the withdrawal thereof throughthe staple, said pin being provided with a longitudinal ridge fitting ina slot extending from the eye of the staple and preventing the rotationof the pin or the wrapping of the ends of the seal about the pin,whereby the withdrawal of the pin before the seal is removed isprevented, substantially as described. y

3. The combination with the staple c, of a hasp a fitting over the same,a pin containing the seal-lock and comprising the shell d provided atthe upper end with a shoulder or lateral extension and provided intheend with the transverse slots d4 d4, the plunger e extending into saidshell and provided with the transverse slot registering with the slotsd4 d* when the plunger is thrust in, said plunger IOO IIO

being` provided with a, peripheral channel e5, In witness whereof Ihereunto subscribe my a pin or proj eotion on the shell extending intoname this 4th day of April, A. D.' 1896. Said peripheral channel tolimit the movement of the plunger, and a catch for looking said 5plunger within the shell when thrust in eX- /Vituesses:
